Why phase modulation is used?
Actually phase modulation was used for the color signal in all analog TV systems.Phase modulation, with some signal preprocessing, was used to indirectly get frequency modulation in many FM transmitters.Certain modems use phase amplitude modulation.etc.
What is ppm modulation?
pulse position modulation, used in many RC model aircraft controls.
In order to send more than one bit at a time during a single phase on a carrier modulation is used?
amplitude modulation is used
What is Modulation index in Frequency modulation?
Modulation Index is the ratio of the maximum deviation frequency to the frequency of modulation. In other words it is the ratio of the spread in frequency spectrum to the frequency that was used to modulate the carrier. For FM, modulation index is given by the formula mf= df/f where, mf=modulation index for FM df=difference in carrier frequency f=frequency of the signal
Which modulation technique is used in gsm?
GSM uses GMSK modulation scheme. GPRS also uses GMSK modulation scheme. EDGE and UMTS uses 8-PSK.
What does Base stand for in 100BaseT?
"Base band", meaning that no modulation is used."Base band", meaning that no modulation is used."Base band", meaning that no modulation is used."Base band", meaning that no modulation is used.
Where is delta modulation used?
Adaptive delta modulation is used in audio communication systems to avoid the two drawback of delta modulation.
What modulation is used in telegraphy system?
pulse code modulation method used a telephony.
Where is adaptive delta modulation used?
Adaptive delta modulation is used in audio communication systems to avoid the two drawback of delta modulation.
What is use of time delay in adaptive delta modulation?
It is used to delay the modulation
When does modulation take place?
If you speak loudly then softly you have used modulation of your voice
What type of modulation is used to carry the picture portion of a television signal?
Amplitude Modulation (AM) is used for the picture portion of a television transmission while Frequency Modulation (FM) is used for the audio portion.
Why phase modulation is used?
Actually phase modulation was used for the color signal in all analog TV systems.Phase modulation, with some signal preprocessing, was used to indirectly get frequency modulation in many FM transmitters.Certain modems use phase amplitude modulation.etc.
Why phase modulation is least used?
